FILLING-IN ATTACHMENT FOR PRINTING-MAOHINES.

Application filed November 15, 1911.

To all whom it may concern:

Be it known that I, ERNEST DUsoHER, a citizen of the United States,residing at La Crosse, in the county of La Crosse and State ofWisconsin, have invented a new and useful Improvement in Filling-InAttachments for Printing-Machines, of which the following is aspecification.

My invention relates to improvements in printing machines and its objectis to provide a type bed which may be introduced on the main type bed ofthe machine in connection with type forms thereon, to carry asupplementary form exchangeable and adjustable with relation to theother forms carried by the machine.

In connection with this main object my device is adapted to theinsertion and removal of supplementary type forms such as are used inprinting different Salutations on copied letters and in printing theaddresses on envelops, and to the automatic regulation of the ribbonduring the changing of the forms.

Further objects will be apparent from the following description.

My device is simple in construction and accurate in operation,.theparticular form shown being especially adapted but not necessarilyconfined to use in connection with a printing machine such as describedin applicants companion application Serial No. 652,105, filed Sept. 30,1911, for printing machines and improvements thereon.

In the drawings with which I have illustrated my invention and whichform part of this specification, Figure 1 is a plan view of a printingmachine of the class mentioned equipped with my improvement; Fig. 2 is aview on the line XX, Fig. 1 showing a side.

Serial No. 660,425.

form mounted in printing position on the printing block, and Fig. 10 isa detail in section showing a portion of the type form and one of itstype.

In the above drawings I have shown a printing machine having asupporting frame, a type bed B carried by the frame A, on which a form Cmay be supported, and with which a traveling platen D cooperates inmaking a printing impression. My sup-' plementary type bed or printingblock E is shown mounted on the type bed B and carrying a supplementarytype form, type holder or name plate F which is so positioned by theprinting block E as to cooperate with the platen D in the same manner asthe form C on the bed B.

On the frame A are mounted sprocket wheels 2 carrying sprocket chains 3at each side of the machine on which is mounted the platen D in the formof a roller which traverses the type form and having a Wear wheel 5 ateach end through which printing pressure is imparted to the platen. Thetype bed B is so positioned with relation to the path of the platen Dcarried by the sprocket chains 3 that the platen normally travelsorbitally about the type bed, and above the surface of the type in theform and out of contact with it.

Printing pressure on the platen is secured by means of pressure bars 6at each side of the machine under pressure from the spring 7 which maybe adjusted to different degrees of pressure. The under surface of thepressure bar 6 is formed with rectangular notches 8 which bear upon aportion of the periphery of the wear wheels 5 producing an intermittentpressure and repeated impacts on the platen and thereby on the form.

A tabulating rail 9 is shown at each side of the machine on whichtravels the wear wheel 5. The upper surface of the tabulating rail isformed with a steel ribbon 10 resiliently mounted on it by means ofwhich local adjustments of pressure on the form may be secured.

' A color inking ribbon 1.1 is mounted on the machine between the pathof the platen and the type form and is carried over suitable rollers 12connected by gears 11 with the sprockets 2 to be operated. An operatinghandle 15 connected with one pair of sprockets 2' operates theplaten ,Dandthe ribbon 11 in the usual manner, that is the ribbonis steppedacross the bed or type form at suitable intervals while the handle isturning, the ribbon remaining stationary while each impression is beingmade. The specific construction for accomplishing this result is notshown, any form being adapted for use with my invention andnotconstituting part thereof. Two .forms for accomplishing this result areillustrated and described in' Patent No. 1,014,094, issued to lVilliamA. Sorg on the 12th day of November, .1912, and in my application forpatent, Serial No. 681,382, filed on March 1, 1912.

My supplementary type bed or printing block E consists ofa body part 16of comparatively narrow width and extending transversely across the typebed and parallel with the line of motion of the platen D. The body 16rests directly on the type. bed

. B on which .it is adjustable vertically by means of setscrews 17,thisadjustment being permanent when once made, to bring the printingsurface 18 to such an elevation that standard type 19 in thesupplementary type form F have an equal elevation with the type commonlyused in the form C on the bed B. V y

The printing surface 18 as commonly used for addresses or Salutationsextends less than the width of the type bed B, and at both ends oftheface 18 the body 16 iscut away or depressed in elevation so that thetype in the form F when resting on or above these-parts of the body 16do not have printing contact with the ribbon 11 during the passage ofthe platen D. r

The sides of the body 16 are formed with grooves 20 extending the fulllength thereof for the engagement of the name plate F which is formedwith lugs 21 adapted to travel in the grooves 20 during the longitudinalmovement of the plate F along the printing block. The lugs 21 extenddown the sides of the printing block and into the grooves 20 andallowthe type 19 carried by the name plate to rest upon the printingsurface 18 when the name plate has reached that part of the block.Aspring 22 is fixed a on one side of the block Eby means of a The springhas contact tips 24 and 25 adapted to lie between the lugs 21 on oneside of the name plate F when the name plate is in printing position onthe printing surface 18. The spring tip 24 has a beveled surface adaptedto permit the movement of the name plate toward the tip 25 while the.tip 25 is seated in a notch 26 in the block and presents an abrupt facepreventing the return movement of the name plate when once engagedby it.As the name plate is moved along the blockE the front lug 21 of theplate engages the spring 24: and passes under it and moves on opening upthe tip 25 by pressure from inside. lVhen the tip 24 engages the rearlug 21 of the plate its pressure is instantly felt by the operator aswell as the release of the tip 25 which at the same instant drops behindthe forward lug 21. The movement of the plate is thus stopped and forthe purpose of printing it is firmly held on the block but it may beadvanced by the operator and moved off the block in the same directionin which it was moved onto the block.

An extension 27 having thesame width as the block E is connected withthe block by means of screws 28 and extends beyond the machinepermitting a plate F to be pushed from the block and from under thecolor ribbon 11. The movement of the plates F along the block isaccomplished by means of a pusher 29 which slides in a slot in the blockon a rod 30 which is mounted on the block. A spiral compression spring31 is mounted on the rod 30 in front of the pusher 29 and is compressedby it during the forward movement of the pusher in advancing the plateand upon the release of the pusher returns it sharply and automaticallyto its original position. The pusher 29 is formed flush with thedepressed surface of the approach of the printing block and is adaptedto be operated by hand such as by the finger or thumb of the printer. Inorder to secure the engagement of the end of the name plate F by thepusher a spring stop 32 is mounted The recess 33 is short and when thepusher i isadvanced to engage a plate the end of the stop 32 is forcedupward to the level of the normal surface of the rod 30 thus forcing itsupper extremity above the level of the pusher as illustrated in Fig. 6where it is adapted to engage the edge of a plate F and advance itduring the further movement of the pusher.

As soon as the pusher has returned to the position shown in Fig. 1 thestop 32 is retracted by the action of the spring 34 and the paper isfree to travel out of the machine without obstruction.

To prevent the interference of the plates F and the ribbon 11 duringtheir advanceting the platen to bring the ribbon into contact with thetype without resistance, and is formed of smooth wire to permit theunobstructed travel of the ribbon.

The body 16 of the block E rests upon the bed B, the approach extremityof the block is in contact with the bar 37 of a supporting bracket 38which is mounted on the type bed B being fixed adjustably to the edge ofthe type bed. by means of tap screws 39 and set screws e0 which areadapted to adjust the elevation of the bar 37 to any desired point. Thebracket is formed with an angle shaped part 41 embracing the corner ofthe type bed B and the longitudinal movement of the block E is preventedby lugs 42 and L3 lying transversely on the under surface of the blockwhich engage the upper leg of the angle part 41.

In operating my device it is positioned on the type bed at the same timethat the form C is placed thereon and is fixed laterally with relationto the ends of the type bed (by spacing blocks) in the usual man ner.The ribbon is placed above it in printposition resting on the spring 35.The first name plate is then placed on the printing block E and afterproper adjustment of the form C and pressure bars 6 paper is placed onthe ribbon and the platen is operated in the usual manner producing aprinted impression from both the form C and the plate F at the sametime.

When it is desired to change the name plate F a new one is placed on theapproach of the printing block and the pusher 29 is advanced moving theplate F forward on the block. The first used plate F is forced off theprinting surface 18 along the block toward the extension 27 from whichit may be removed by hand.

The replacing of the plates F on the block may be accomplished withoutinterrupting the operation of the printing machine be tween the passagesof the platen over the form. For convenience in positioning sheets orenvelops on the type forms paper guides a5 and 16 of different lengthsmay be mounted on the machine said guides 15 also acting as lifters forthe paper. Strippers 1-? may also be used to engage the lifted sheetsand envelops and remove them from the machine. Paper slides 48 aremounted on the bar 37 to deliver printed sheets from the machine. Theseguides, strippers and slides will. be found fully described in mycompanion application above referred to.

The name plateor supplementary type form F has the form of a plate withaseries of slots 50 in which are mounted suitable double shouldered type19 adapted to engage the side of the slots for support to preventlateral movement of the type when in printing position and to hold thetype assembled when not being used in the machine. Each of two oppositesides of a ype has two shoulders 51. The type 19 are laced in the slots50 in suitable form for printing salutations, addresses and the like andare locked in the slots by compressing the shoulders of the type at theend of the series or of a suitable blank similarly located, intoengagement with the sides of the slot 50. The grooves between theshoulders 51 of the type on each of two opposite sides of the type inwhich the sides of the slots 50 in the name plate engage are ofsuflicient width to enable each type to engage the name plate freely andto rest on the raised surface of the block without being supported bythe name plate during printmg.

The end portions of the plate are depressed below the level of the typebearing slots which are open at one end to receive type. The endportions of the plate described have depending lugs 21 formed integralwith the plate at each corner of the plate for engagement with thegrooves in the sides of the printing block as described.

The manner in which the type are fastened to the name plate so that theycan move up and down between their shoulders 51 permits the type tostand in printing position, vertically independent of said plate aSillustrated in Fig. 9, with their lower ends resting on the raisedportion 18 of the block and in non printing position as illustrated inFig. 10 before and after the plate is positioned on said raised portion.

It is evident that my printing block may be used in the present ormodified form in connection with any machine of the class described inwhich a type bed, an inking ribbon, and a traveling platen cooperate. Itis also evident that for different purposes the length of the printingsurface on the block may be increased with relation to the type bed andthat if desired a series of printing blocks similar to that described orof any suitable construction may be used in making up a form havingvariable parts.

In accordance with the patent statutes I have described the principlesof operation of my invention together with the apparatus which I nowconsider to represent thebest embodiment thereof but I desire to have itunderstood that the construction shown is only illustrative and that theinvention can be carried out by other means and applied to uses otherthan those above set forth within the scope of the following claims.
